Forecast Discussion

Space Launch Delta 45

High pressure positioned over Virginia will bring easterly winds across the Space Coast today, moderating temperatures. On Monday, a low pressure system will develop in the Great Plains region, but high pressure will remain in control over Central Florida, keeping favorable launch conditions at the Spaceport. The primary weather concern Monday is the Cumulus Cloud Rule, associated with the flow around the periphery of the high pressure area. On Tuesday, expect much the same conditions as high pressure continues to dominate the Southeast U.S., pushing the low pressure area into the Mid-West. The primary weather concern remains the Cumulus Cloud Rule.
